Predict the simple structural behaviour of the following:

a) A steel portal frame overloaded at the bolted joint with the column.

b) A concrete lintel only has an end bearing of 50 mm above a window at each end.

c) The amount of stress that a concrete foundation can take is 30 N/mm2. You know that a future loading will be 50 N/mm2. What will happen to the concrete?
